BURRELL, OF NUTLEY, NEW' JERSEY, ASSIGNOR TO MAoARTI-IUR CONCRETE PILE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK COMPOSITE PILE Application filed May 14,

This invention relates to composite piles and method of making them and particularly to means for tying a shell mold onto a pile section and for holding the sections of a composite pile together.

Piles of the character referred to are formed by driving a wooden pile, placing a metallic shell on the top of the wooden pile, and filling the shell with concrete. It is essential that the shell be firmly anchored to the wooden pile or to the lower pile section when the concrete is being poured in order to prevent escape of the concrete and also to form a rigid composite pile structure.

The invention has for its salient object to provide a simple, practical and effective method of making a structure of the character described in which the shell is anchored firmly to the lower pile section.

Another object of the invention is to provide anchoring or securing means of the character specified that is simple in construction, comprises a minimum number of parts, and can be easly and quickly utilized to perform the desired functions.

Further objects of the invention will appear from the following specification taken in connection with the drawing which forms a part of this application, and in which Fig. 1 is an elevational view, partly in section, of a composite pile having shell securing means constructed in accordance with the invention;

Fig. 2 is a plan view of the pan in which the lower end of the shell seats;

Fig. 8 is a bottom plan view of the shell; and

Fig. 4 is a perspective view showing the construction of the tie rod which connects the wooden or lower pile section to the shell.

The invention briefly described consists of a composite pile and a method of making it, which pile comprises a lower section having a reduced upper end or tenon and an upper section comprising a metallic shell which is mounted on the lower section and is secured in tight engagement therewith by an anchoring rod and filled with concrete. The rod is provided with hooks at the lower ends which engage a transverse pin carried by the 1931. Serial No. 537,290.

tenon. A cross bar is secured to the end of the rod and rests on the top of the shell.

Further details of the invention will appear from the following description.

In the embodiment of the invention illustrated, there is shown awooden pile section 10 having an upwardly extending tenon 11 through which extends a transverse pin 12.

A pan 13 having a central opening 14 rests on the upper end of the section 10 and surrounds the tenon 11. The pan is preferably secured in place by spikes 15.

A metallic shell 20, which is preferably corrugated, has its lower end bent inwardly, as shown at 21, and upwardly, as shown at 22. The portion 21 rests in the pan and the portion 22 surrounds the tenon 11. In order to facilitate the position of the shell in the pan, the lower end of the shell has formed therein oppositely extending notches 23 which permit the'passage of the ends of the pin 12 therethrough.

After the shell has been placed in position, as shown in Fig. 1, an anchoring rod 25 is placed in the shell. The rod is forked or bifurcated at its lower end to provide legs 26 and 27 and oppositely extending hooks 28 and 29 are formed on the lower ends of the legs. The rod is lowered in the shell until the upper ends of the hooks are disposed below the cross pin 12, whereupon the rod is rotated and raised to the position shown in Fig. 1 in which the hooks engage the ends of the pin 12. A cross bar 30 is secured to the upper end of the rod and rests on the top of the shell 2O. The upper portion of the rod is preferably threaded, as shown at 31, the cross bar 30 being secured by a nut 32.

After the tie rod or anchoring rod 25 has been secured in position as above described, the concrete is poured into the upper end of the shell and the shell is substantially filled.

From the foregoing description it will be seen that simple, practical and efficient means have been designed for securing the shell of composite piles to the lower or wooden pile section. It will furthermore be evident that the anchoring rod can be easily and quickly secured in position.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

i 1. In combination, a pile section having a body, a tenon of smaller diameter than that of the body and a shoulder formed between the body and the tenon, studs projecting laterally from the tenon, a metallic shell of larger internal dimension than that of the tenon resting upon the shoulder and extending upwardly from said pile section, and means for connecting the upper end of the shell with said studs to hold-the lower end of the shell on said shoulder,'said means including a member disposed upon the top of the shell but having an opening therethrough to permit concrete tobe poured therein.

2. In combination, a pile section having a body, a tenon of smaller diameter than that of the body and a shoulder formed between the body and the tenon, studs projecting laterally from the tenon, a metallic shell of larger internal dimension than that of the tenon resting upon the shoulder and extending upwardly from said pile section, means extending across and upon the upper end of the shell and leaving a portion of said upper end open to receive concrete, and a member connecting said bar with the studs and arranged to hold the lower end of the shell on said shoulder.

3. In combination, a pile section having a body, a tenon of smaller diameter than that of the body and a shoulder formed between the body and the tenon, studs projecting laterally from the tenon, a metallic shell of larger internal dimension than that of the tenon resting upon the shoulder and extending upwardly from said pile section, a bar across and upon the upper end of the shell, a member having a lower bifurcated hooked end engaging said studs, and an upper end connected with the bar and arranged to hold the lower end of the shell on said shoulder.

4. In combination, a pile section having a body, a tenon of smaller diameter than that of the body and a shoulder formed between the body and the tenon, studs projecting laterally from the tenon, a metallic shell of larger internal dimension than that of the tenon resting upon the shoulder and extending upwardly from said pile section, abar across and upon the upper end of the shell, a member having a lower bifurcated hooked end engaging said studs, and an upper threaded end passing through the bar and a nut thereon arranged to hold the lower end of the shell on said shoulder,

5. In combination,-a wooden pile section having a body, a tenon of smaller diameter than that of the body and a shoulder formed between the body and the tenon, a pin passing through the tenon, the ends thereof forming laterally projecting studs, a metallic shell of larger internal dimension than that of the tenon resting upon the shoulder and extending upwardly from said pile section, a bar disposed across and upon the upper end of the shell and leaving a portion of the upper end open to permit concrete to be poured therethrough, and a member connecting said bar with the studs and arranged to hold the lower end of the shell on said shoulder.
